It's essential to maintain proper care of the plant to help prevent and manage any potential infestations or infections.
Common Pests
One of the common pests that might affect Euphorbia celastroides is mealybugs. These insects suck nutrients from the plant and can cause stunted growth and deformity of the plant. To manage mealybugs, owners of the plant must use insecticides that contain neem oil or soap-formulated potassium salts. Another common pest that can infest the plant is scale insects.

If the infestation is severe, applying a systemic insecticide or using a horticultural oil can be effective.
Common Diseases
Common diseases that affect Euphorbia celastroides include stem rot, root rot, and powdery mildew. Stem and root rot cause by overwatering or underwatering the plant. This leads to the roots becoming infected with fungus, which can cause the plant to wilt and die. To manage stem and root rot, it's essential to remove infected roots and soil. Then, propagate the healthy portions of the plant in fresh soil. Powdery mildew is a fungal disease that is prevalent in humid conditions. It can cause white spots on the leaves and stunted growth of the plant. Owners can manage powdery mildew by ensuring the plant has proper air circulation and watering from the bottom of the plant, avoiding moisture on the foliage.
By adequately managing pests and diseases, Euphorbia celastroides Boiss. var. haupuana Sherff can thrive and grow to its full potential. With routine inspections and proper care, owners can enjoy this lovely succulent with minimal issues.
